to give you advice.
This is how I recruited Mew last night, of course you do need his friend area which can be purchased from Wigglytuff.
Bring a friend bow, and at floor 36 when you have the Music Box (orgel) try to find the stairs, going about normal adventures. Watch your dialogue box closely. Move about 20 times on each floor even if you know where the steps are. If Mew is on that floor, it will say in 20 turns "Mew used transform" if you see this kill every pokemon on that floor to find him.
I saw him 4 times, on floor 59, 49, 60, and then I recruited him on floor 81.
